delphitools
A collection of small, low stakes and low effort tools.
No logins, no registration, no data collection. I can't believe I have to say that. Long live the handmade web.
If you find these tools useful, I'm glad. You don't owe me anything. But if you're an artist, feel free to email me your work. I'd love to see it.
If you would like to donate to delphitools, I ask that you don't. Make a donation to Wikipedia (opens in new tab) or the EFF (opens in new tab) instead. Email me your proof of donation and I'll put you in the credits.

About
delphitools is a collection of small, focused utilities that respect your privacy and work entirely in your browser. No data leaves your machine, no accounts required, no tracking. Just tools that do what they say.
I love the web. The classic, real web full of weird things. And that web is out there. You just have to find it. And sometimes, you have to make it yourself.
